I love videos like this, because they stimulate lots of interesting debate.

For the record, I do think Earth is a sphere, and I do think they managed to land men on the moon. But at the same time, much NASA material is very obviously edited, or is misleadingly presented.

Some of those "space walk" videos are clearly recorded from their underwater training facilities, of which they have two: I don't buy the "ice crystals" explanation at all. And I don't doubt that some of the ISS videos are green-screened using harnesses.

Similarly, in the moon landing photographs, there are numerous examples where the exact same terrain was spliced into the backgrounds of shots purportedly taken looking in opposite directions, with totally different elements in the foregrounds.

Most of the raw moon shots either probably didn't develop properly, or were extremely boring. Considering they spent the GDP of several small countries combined to get there, the real pictures probably wouldn't sit well with the public-- so they were embellished, to make them look cooler.

This worked in the grainy, low-res newspapers of the time, but under internet scrutiny where dozens of pictures can be lined up for side-by-side comparison in seconds, the inconsistencies become very obvious.

The ISS is real, because you can catch it with well-timed telescope shots right from your back yard. But if people can't get a "Zoom" meeting working from Minneapolis to St. Paul half the time, try doing one moving at 17,000 mph-- especially when a much cheaper to make training harness segment will educate the public too.

Like most things, the truth is probably in the middle: NASA does have people in orbit and did have them on the moon, while many of the arm chair analysts at home are right on the money in picking up on some edited and misrepresented material.
